A couple of things:

1) You should run a newer version than 0.9.9.  That version was released...a while ago.  1.0.0 is the current version, and 1.1.0 is on the way.  I think Ubuntu/Debian has a package available, but it hasn't been maintained by anyone recently, so it's several years behind.

2) Regarding the error you're seeing, is guacd actually running?
